Citrix multiple virtual channels

From ThinOS 9.1.3112 and later versions with Citrix Workspace app 2104 and later, ThinOS Citrix UC Virtual Channel Settings and Other Citrix Virtual Channels Settings are deprecated. The configuration changes that you make to the Admin Policy Tool or the Wyse Management Suite policy settings does not affect the Citrix multiple channel settings since multiple virtual channels are always enabled on the thin client. However, ensure that you uninstall the Unified Communications (UC) packages that are not required, to prevent the consumption of server and client resources. Dell Technologies recommends that you install the Citrix Workspace app package first, and then install the Citrix Unified Communications package.

Citrix UC Virtual Channel Settings and Other Virtual Channel Settings in the Admin Policy Tool or Wyse Management Suite server are only applicable for ThinOS 9.1.2101 or earlier versions. From ThinOS 9.1.3112 to 2208 (9.3.2102), Admin Policy Tool does not sync the Citrix Unified Communication Virtual Settings and Other Virtual Channel Settings from Wyse Management Suite policy settings.

The following combinations of UC optimizations and their virtual channel settings are tested on ThinOS 9.1.2101 and 131:

Table 1. Unified Communication optimizations and their default virtual channel settingsUnified Communication optimizations and their default virtual channel settings
Virtual Channel categories Settings Default status Combination 1 Combination 2 Combination 3 Combination 4 Combination 5 Combination 6 Combination 7
UC Virtual Channel Settings Microsoft Teams Optimization Enabled Enabled Disabled Disabled Enabled Disabled Enabled Disabled
RTME for Skype for Business Enabled Enabled Disabled Disabled Disabled Disabled Disabled Enabled
Zoom Meetings Optimization Disabled Disabled Disabled Enabled Enabled Disabled Disabled Disabled
JVDI for Cisco Jabber Disabled Disabled Disabled Disabled Disabled Enabled Disabled Disabled
Cisco Webex Meetings for VDI Plugin Disabled Disabled Enabled Disabled Disabled Disabled Disabled Disabled
Cisco Webex Teams for VDI Plugin Disabled Disabled Enabled Disabled Disabled Disabled Disabled Disabled
Other Citrix Virtual Channels Settings USB redirection Enabled Enabled Enabled Disabled Disabled Enabled Enabled Enabled
Imprivata Enabled Enabled Enabled Enabled Disabled Enabled Enabled Enabled

In ThinOS 9.1.2101 and earlier versions, Zoom Meetings Optimization plug-in uses four virtual channels. To use Zoom Optimizations along with Microsoft Teams or any other Cisco optimizations, you must disable other virtual channels. For example, if you are not using Imprivata SSO, you can choose to disable the Imprivata virtual channel. Similarly, if you do not use Skype for Business, you can choose to disable the RTME for Skype for Business virtual channel.

NOTE:The UC Virtual Channel settings do not apply to ThinOS versions later than 9.1.2101 but earlier than or equal to 2208 (9.3.2102). These settings are supported again from ThinOS 2211 and later. From ThinOS 2211, the default values of all UC virtual channel settings have been changed to Enabled.
NOTE:When the UC virtual channels are disabled, the Unified Communication software on ThinOS uses the fallback mode, which uses the HDX webcam and HDX audio. Using the fallback mode consumes more remote desktop resources such as CPU, GPU, RAM, and Network.
NOTE:Enabling or disabling the UC plug-in settings in VDI Configuration Editor > Citrix Configuration Editor is deprecated from ThinOS 2211.

For ThinOS 9.1.2101 or earlier versions, see ThinOS 9.1 Administrator's Guide at www.dell.com/support on the number of allowed virtual channels and tested combinations of Unified Communication optimizations.
